ABRASIVE WHEEL.

SPECIFICATION forming part of Letters Patent No. 248,093, dated October 11, 1881. Application filed July 9, 1881. (No model.)

To all whom 'it may concern:

Be it known that we, GEORGE A. 'FULLER- ToN and FREDERICK W. CoY, both of Boston, in the county of Suffolk and State of Massachusetts, haveinven ted an Improved Abrasive Wheel, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, makinga part hereof, ill which- Figure 1 is a side elevation. Fig. 2 is a vertical section. Fig. 3 is a section of the band bearing the abrasive material. Fig. 4 is a section on line xx, Fig. 3.

,Our invention relates to the means of securing the sand-paper or other abrasive material to the wheel; and it consists in the combination, with the wheel or roll, of a lexible band, which is adapted to be tirmly secured tothe wheel or roll, and also to support thc sand-paper and hold it in its place.

In the drawings, A represents a wheel such as is used for sandpapering the Shanks and heel-edges of boots and shoes, and- B a band for supporting the abrasive material. This band B is composed of a strip ot' leather, b,

having upon its ends` metallic pieces Ig b2, by

which it is `secured to the periphery ot wheel A.

The piece b may be attached by screws, as shown, or in any other convenient way, as it is not necessary to remove it from the periphery of wheel A except when a new felt Astrip is needed'.

The piece b2 is attached to the leather strip b, as shown in Fig. 3. The leatheris properly trimmed to make its under side flush with the metal piecel)2 and its upper side ush with a strip of metal, 113, placed thereon to receive the ends of the'rivers, which pass through all three and secure them` together. It is also trimmed to a tapering point to lit between the inner ends of these metal pieces, whichre beveled for that purpose.

l The outer ends of the metal pieces lie close together, and haveV because the felt strip b3 is more readily connected with leather than with metal.

In applying the sand-paper one end of the strip 0 is inserted in the slot a, and the other end is folded over the metallic piece b2, one end of band B being disconnected from wheel A. for the purpose. This is clearly shown in Fig. 2, where C represents the strip of sandpaper. After the paper has been thus applied to the band the free end of theband is secured tothe wheel by placing the metal piece b2 over the button a. As this button a is eccentric on its shaftaz, turning that shaft half round will carrythe button from its position in Fig. 2 nearer to the piece b of band B, and thereby strain band B over the periphery of wheel A, Button a is then depressed, so as to force piece b2 close against the sand-paper lying between itrand the periphery ot' wheel A. The shaft a2 is provided with the finger-piece a3, by which it can be readily' turned, and with the nut a4, by which the button a can be depressed.

Other devices` may be used for these purposes,

as will be obvious.

One endot' the paper may, of course, be vlam peil between piece b and the periphery of wheel A; but the slot a answers well, and obviates the use of any mechanical device for causing the piece b to act asa clamp.

Our invention is applicable to buftiug or scouring rolls, as well as to shank-wheels, the band B being made wider and two or more fastening devices being used instead of the singlebutton a. Y

l. Inanabrasive wheel, the combination, substantially as described, with the wheel or roll, of a flexible supporting-band, over which theabrasive strip is stretched, and between which and the wheelIone end of the abrasive strip is secured.

2. In combination with wheel A and band B, 'the eccentric button a', its shaft a2, and means,

substantially as described, for turning and lowering the shaft a2, in order to strain the band around the wheel and to force the end of the band close against the wheel.
